Title: Ultrahigh speed optical waveform measuring equipment
Inventor: KITAMURA ATSUSHI
IPC: G01J11/00
Filed: 1994-09-22
Abstract: PURPOSE: To obtain an ultrahigh speed optical waveform measuring equipment for measuring the waveform of a signal light over a wide waveform range. CONSTITUTION: A signal light source 5 outputs a signal light 5a oscillating at an arbitrary angular frequency while a gate light source 6 outputs a gate light 6a oscillating at a constant angular frequency and a GT prism 7 polarizes the signal light 5a linearly. A PBS 8 polarizes the gate light 6a linearly and a BS 9 multiplexes both lights on a same optical axis. A nonlinear crystal 11 converts a part of both lights into a sum frequency light 11a and a waveform setting section 14 commands a ROM 13 to deliver a data. Based on the data, a control circuit 12 shifts the nonlinear crystal 11 through a shifting stage group 10. An optical HPF 15 takes out the sum frequency light 11a from the nonlinear crystal 11 and a light receiver 16 converts the sum frequency light into an electric signal proportional to the intensity of light.  Upon receiving a trigger signal from a mixer 19, the waveform is reproduced at a display section 18.

Title: Manufacture of semiconductor memory device
Inventor: ITO HIDEKI
IPC: H01L21/8242
Filed: 1990-09-27
Abstract: PURPOSE:To reduce a cell area by forming a contact hole through a plate electrode of a capacitor and by forming a data line connection part inside an insulating film sidewall of the contact hole. CONSTITUTION:Insulating films 29, 28, a polysilicon film 27 and an oxide film 24 are etched using a resist pattern 30 as a mask. Thereby, a contact hole 31 for data line connection is shaped in the films 28, 29, 24 passing through the film 27 as a plate electrode of a capacitor. After the pattern 30 is removed, an insulating film 32 is formed in an inner wall of the hole 31 and on a surface of the film 29, and it is etched to form a sidewall 32a of an insulating film only in a side wall of the hole 31. Thereafter, a data line 34 is formed, which is connected to a diffusion layer 33 through the hole 31 inside the hole 31 and on a surface of the film 29. Since an interval between a plate electrode and a contact hole can be made only the width of a sidewall, a cell area can be reduced.

Title: Lithium ion secondary battery and manufacture thereof
Inventor: MINAFUJI TAKESHI
IPC: H01M10/05
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a battery having high reliability while eliminating harmful effects of the preliminary charge by housing a plate group formed of a positive plate and a negative plate wound though a separator and the electrolyte in a battery case, and performing the pressure reduction at the predetermined air pressure during or after the preliminary charge, and sealing an opening part of the battery case.

Title: Vertical amplitude correction device
Inventor: OKAZAKI TOSHIHIRO
IPC: H04N3/22
Filed: 1990-09-25
Abstract: PURPOSE:To correct the fluctuation of vertical amplitude in response to the lightness of the screen by using a control voltage of an automatic beam current limit circuit so as to control dynamically an adjustment voltage of a vertical amplitude. CONSTITUTION:A level shift transistor(TR) 12 connects to a beam current detection terminal of a flyback transformer FBT 2, its output connects to amplifier TRs 13, 14 and further its output connects to a gate terminal of a FET 15 fitted to a feedback circuit of a vertical deflection coil DY. Thus, when the screen gets dark, the beam current is reduced resulting that a current flowing to the anode is reduced and a control voltage of an automatic beam current limit circuit ABL is increased. When the screen is bright, the beam current is increased, the current flowing to the anode is increased and the control voltage is decreased. Thus, the control voltage is utilized to control the adjustment voltage of a vertical amplitude thereby reducing the fluctuation in the vertical amplitude.

Title: On-vehicle communication equipment
Inventor: IKEDA JUNICHI
IPC: H04W88/02
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To provide the on-vehicle communication equipment in which communication quality is improved with a simple and inexpensive configuration. SOLUTION: Before a vehicle C passes a front position of a beacon 10, the communication equipment selects an antenna 22a whose directivity is directed in a forward direction C1 in which the beacon 10 is in existence (P2). In the case that the vehicle C passing the front position of the beacon 10 is detected from a change in a phase of an AM component, the communication equipment selects an antenna 22b whose directivity is directed in a backward direction C2 in which the beacon 10 is in existence (P3). In the case that it is detected from a reception level Rr decreased less than a threshold level Rr TH that the vehicle C is retired from the service area of the beacon 10, the communication equipment selects the antenna 22a again to prepare for the travelling to a succeeding service area (P4).  Thus, since the antenna directivity is switched in only a limited timing, the communication quality is improved with a simple and inexpensive configuration.
